چکیده انگلیسی
We have investigated a honeycomb microhole network of Pb film by a SQUID magnetometer and a SQUID microscope. A negative pattern of honeycomb network of photoresist has been fabricated by an electron beam lithography. A film of 200-nm thickness was prepared by the evaporation of Pb on the photoresist pattern, where the silicon substrate is 4 Ã 4 mm in size. The period of the network is 7.4 μm and line width is 1 μm. We found the matching effect in a M-H curve of the Pb honeycomb network by the SQUID magnetometer. The applied field ranges from â4.7 G to +4.7 G. Vortex configurations in the honeycomb network of the period 15 μm and line width 2 μm have also been observed by the SQUID microscope. We suggest that vortices form some local triangular configurations at lower temperatures.
